Be it known that I,- JOHN T. 'McCRA'w, a

citizen of the UnitedfStatesfiresiding at Avlesworth; in the county of Marshall and State of Oklahomafhav'e-invented new and useful Improvements in Cattle-"Guards, of which the following is a s'peci'fication.'

This invention relates to new and useful improvements in cattle guards and 'the principal object of the invention is to provide a guard which will prevent jthe cattle passing while at the s'am'e time will notinju're*the cattle in any way. Another object of the invention is the provision of inclined frames placed on'e'a'c h side" and between the rails of the track and carrying transversely arranged rods on which are mounted a plurality of rollers spaced apart by washers so that an animal attempting to pass over the frames will be caused to slip back to the starting point.

Another object of the invention is to provide fenders for the raised ends of the frames to protect the guard from injury by hanging bars or the like on the train.

Another object of the invention is to pr0- vide a device of this character which is simple and durable in construction, reliable and efficient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a plan view of the invention.

Fig. 2 is a longitudinal section.

Fig. 3 is an enlarged detail view showing the arrangement of rollers and washers.

In these figures A indicates the rails of the track and B the ties thereof while 1 indicates the parts of the guard located on each side of the track and 2 indicates that part located between the rails. Each part of the guard consists of a number of parallel bars 3 lying parallel to the rails and having perforations therein to receive the bars or bolts 4. These bolts may be held in place by any suitable means, asshown they are each provided with a head on one end and the other end. screw threaded to receive a nut. These bolts receive a plurality of rollers 5 which are spaced apart-by thesleeves orwashers 6. As will be seen the rollers 'on adjacent bolts are arranged in staggered formation so that a roller on one bolt is located between a pair of rollers on theadjacent boltsl The rollers and 'sleeves'are of such dimensions as to. permit the free movement of the rollers on the bolts, but I prefer to make the spaces between theparts small so as to prevent an animals foot pass- "ing' between the parts. Aswill be seen the three parts of the guard are similarly made though the middle part is much wider than the other parts, and said middle part is provided with a middle rod or bar 3 to support the central parts of the bolts. The parallel bars 3 and 3 are connected together at their ends by the end bars 7 so as to form a complete frame of rectangular formation. The parts of the guard are supported in an inclined position on the ties of the track with their upper ends on a level with the top of the rails and their lower ends located below the top of the tie to which their ends are secured. To so support the parts of the guard I provide legs 8 for the upper ends which have their upper ends secured to the frames and the lower ends suitably secured to the top of one of the ties, said legs being of such length as to support the upper end of the guard level with the top of the rail. The lower end of the guard is secured to the side of the adjacent tie near the bottom side thereof and I may do this by connecting straps 9 to said ends and securing said straps to the tie by spikes or the like. The upper ends of the straps project above the end of the frame and have their upper ends bent at right angles and secured to the top of the tie. To secure this arrangement of parts it may be necessary to replace the tie next to the one to which the bottom of the guard is secured by a tie of less thickness as shown in the drawings at B. To protect the guard from injury by hanging rods and the like on a train I provide fenders 10 which may be formed of any suitable material, such as metal. These fenders have their upper ends suitably secured to the top of the guard, as by being bent around the uppermost bolt, from which the rollers and washers are omitted, and the lower ends of said fenders are Spiked to the tie adjacent so that an animal passing over the crossing and starting to travel over the track would Walk on thelower end and thusf 'if it attempted to walk up the inclined surftwe of the guard the rollers and sleeves would r0- tate under its weight and tllt fi cause the animal to slide back to the a d of the guard- Thus the anima wou d be prevented reiii traveling along the track and at the same time the animal would not be injured by the guard. The sides of the uard are lwated sufficiently close, to the mils 0f the track to prevent an animals foo from passing between the s i g a d and the rails- It is houg t i im the oreg ng de cripion hat h ad antage -and novel features f my invention ill be readily apparent- I desire it to be understood tha I may Copies of thia note-lit may obtained 18 in the combination and arrangement of the "several parts, provided that such changes fall within the scope of the appended claim.

What I claim is In a cattle guard, the combination of the rails and the ties, a frame, a plurality of transverse bars. earried by said frame, upwardly extending legs secured to the top of one of the ties for supporting one end of the rame on a le el with' he rails, down ardly xtending legs connected with the other end of the fram and having their upper ends oomiected ith the top 0f another tie for sup rting said l wereud below the top of Sa tie, l1 shield ove ing the high end of the frame and having'olie and hinged on the uppe m st bar and. its other end cennected ith a tie located beyond said firame and a pluvalitypf r lle s n the remain ng bars,
